PepsiCo Inc. Chief Executive Officer Indra Nooyi is being targeted by Color of Change, a nonprofit racial-justice group that has previously gone after Uber Technologies Inc. and Walt Disney Co.

The organization is pressuring Nooyi to step down from Donald Trump's business advisory council after the president was slow to condemn white-supremacist violence last weekend in Virginia. Campbell Soup Co. CEO Denise Morrison, another Trump adviser, will be a target of the campaign as well, said Rashad Robinson, executive director of the group, which claims 1 million online members.

"We let Pepsi know about 24 hours ago that we would be moving forward on them," Robinson said in an interview on Tuesday. "They are a public-facing company that talks openly about diversity. Their role on this business council is that of an enabler, and they are an enabler to Donald Trump -- not just the policies but the practices that are putting folks in harm's way."

Pressure on Trump's business advisers has mounted since Monday, when CEOs from Merck & Co., Under Armour Inc. and Intel Corp. all stepped down from his manufacturing council. CEOs from Dow Chemical Co., General Motors Co., General Electric Co. and Boeing Co., meanwhile, have indicated they will stay for now. Trump also tweeted on Tuesday that he has many leaders waiting to take the place of anyone who leaves.

"What we're hoping is for these companies to stop, and desert, and leave this administration isolated," Robinson said.

The group also is calling for IBM Corp. CEO Ginni Rometty to break ties with Trump. That puts its focus on three female members of a mostly male group of executives. General Motors Co.'s Mary Barra hasn't been targeted.

PepsiCo declined to comment on the Color of Change campaign, while Campbell didn't immediately have a comment. IBM didn't immediately respond to requests for comment.

It's not the first time Trump has faced defections from his panels. Uber CEO Travis Kalanick left the White House's strategy and policy forum after the ride-sharing company lost customers and drivers who protested his connection with the administration. Disney CEO Bob Iger and Tesla Inc. founder Elon Musk withdrew from presidential panels after Trump decided to pull out of the Paris climate accord.

'Heartbroken' by Violence

The latest criticism of Trump stems from his failure to quickly condemn white supremacists for deadly violence at a rally Saturday in Charlottesville, Virginia. Nooyi, 61, responded to the attacks with a tweet:

Heartbroken by the violence in #Charlottesville. Hate and intolerance are a betrayal of what we stand for as Americans.

Though based in New York, PepsiCo is prominent in Dallas-Fort Worth. It signed on this year as the first title sponsor of the Rev. T.D. Jakes' MegaFest event that drew an estimated 100,000 people to Dallas. PepsiCo also is the parent company of Plano-based Frito-Lay.

Though Nooyi was more vocal than many CEOs in addressing the controversy, Color of Change has said that the tweet alone doesn't go far enough. Its members have begun targeting her on social media with the hashtag #QuitTheCouncil. The group was previously credited with limiting companies' investment in the Republican National Convention last year.

Nooyi has faced backlash in the Trump Era from both sides of the political spectrum. Two days after Trump's victory in November, Nooyi spoke about the reaction of her family and employees to the election results.

"Our employees were all crying and the questions that they're asking, especially those who are not white, 'Are we safe?'" she said at an event sponsored by The New York Times. "I never thought I'd have to answer those questions."

Boycott Threat

Though Nooyi stressed the need to be unified as a country, the comments got PepsiCo placed on pro-Trump boycott lists.

PepsiCo later said that Nooyi misspoke at the conference. Nooyi was referring to a group of employees she spoke to, not all of PepsiCo's workers, a representative said in a statement to the Washington Post. The situation was exacerbated by fabricated accounts of Nooyi saying PepsiCo didn't want Trump supporters to buy their products.

Nooyi, who was born in India, joined the president's Strategic and Policy Forum on Dec. 14 and hasn't spoken out against the administration since then. But the company faced controversy again in April when an ad featuring Kendall Jenner drew flak for seeming to make light of the Black Lives Matter movement.

At Campbell on Monday, a spokesman cited the importance of diversity and inclusion when explaining why Morrison was staying on Trump's council.

"It continues to be important for Campbell to have a voice and provide input on matters that will affect our industry, our company and our employees in support of growth," Thomas Hushen said.
